WWE has put Rey Mysterio and Sin Cara together to build to a WrestleMania 29 match.
You may remember that WWE wanted to do Mysterio vs. Cara at WrestleMania 28 but both of them got injured. WWE was planning to give out luchador masks to everyone in attendance at WrestleMania 28 and then have them wear the masks before the Cara-Mysterio bout so they could set the Guinness World Record for most masks worn in one place at the same time. This is what WWE is building to for WrestleMania 29.
The new Rey-Cara partnership goes deeper than that though. Rey is not 100% right now and the idea is to put him with Cara so they can work together with Rey being hidden some while he works on getting back to 100%. Another idea is to connect Rey and Cara as partners because there’s a feeling that Rey’s fans aren’t connected to Cara just yet.
There has also been talk of Cara and Mysterio winning the WWE Tag Team Titles before breaking up for the WrestleMania 29 match.
